BELT-FASTENER.

Specification of Letters Patent.

Patented Oct. 7, 1913.

Appiication filed July 3, l191e. serial No. 707,441.

My invention relates to a belt fastener,

` and I declare the following to be a full,

clear, concise, and exact description thereof sufficient to enable anyone skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings in which like referencecharacters refer to like .parts throughout the specification.

The object of the invention is to provide a simple, eliicient device,whereby the ends of a belt, such as are employed upon pulleys to turnshaftings, may berquickly unlted in a manner that ,will obviate anytearing of the engaged portions of theV belt. Heretofore, belt fastenershave been of little service in the art, because of the harmful tendencythat they have of tearing the belt. This harmful feature is avoided inthe fastener disclosed in the drawings. j

Other features will also appear by referring to the drawings in which:

Figure 1 isa top planview of the belt fastener, showing fragments of thebelt; Fig. 2 is a perspect-ive View of the fastener; Fig. 3 is a bottomplan view of the fastener; Fig. t is a longitudinal section taken on theline 4 4 of Fig. 1; Fig. 5 is an enlarged detail view in perspective ofa tooth employed; Fig. 6 is a front elevation of the tooth shown in Fig.5; Fig. 7 is a perspective view of the fastener, looking at the undersurface thereof; Fig. 8 is a transverse section of a tooth takenon line8-8 of Fig. 5.

Referring more particularly to the drawings, the belt fastener comprisesa body portion -1-, which may be made of metal or other suitablematerial adapted for the purpose. In order to give iexibility,part-icularly in a longitudinal direction, to plate -1-, so that saidplate will easily bend to conform to the curved surface of a pulley,said plate -1- is made of quadrilateral shaped form. The yieldingfeature is further effected by forming recesses 2-2 in either end ofplate -1- and by having the maximum thickness of plate -1-- in thecenter port-ion as at 3, which thickness gradusually tapers toward bothends 4 and 5, respectively, where the thickness is at a minimum.

From the under surface of plate -1f, there project a plurality of teeth6, each having a curved surface 7 on the side that encounters thegreatest strain from the belt. The curved surface 7 of teeth 6 avoid thetearing or shredding of the adjacent portions of the belt 8. The sideopposite or side A is formed with a fiat surface, whereby the hole madeby the tooth in belt 8, will encompass as small a space as possible, toavoid weakening belt 8. Teeth 6 are provided vvith sharp edges 9, sothat they may easily penetrate belt 8, when 'assembling the fastener.

In order to steady the ends 10 and 11 of belt 8, and thereby prevent anywabbling of said ends, when belt 8 is in action, there is embodied atooth 12 and a tooth 13, similar in all respects as teeth 6, anddisposed at either end of plate --1. Teeth 12 and 13 are locatedcentrally in the rear of teeth 6-6-6 `When the fastener is applied tothe ends 10 and 11 of a belt as 8, teeth 6, 12 and 13 are forced intothe leather and then bent parallel with the adjacent surface thereof. Inthe event, that it is found desirable to remove belt 8 from the pulleyand shaftings, teeth 6, 12 and 13 may be easily bent into open position,whereby the fastener can be easily removed to 'be subsequently replacedon the same or a different belt. When teeth 6, 12 and 13 are foldedover, the flat surface -A- thereof will lie adjacent the surface of thepulley that contacts with `said belt.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In a belt fastener of the character described, a plate, said platehaving a quadrilateral shape, and a maximum thickness in the centerportion thereof, teeth projecting from said plate, whereby to engage theend portions of a belt, said teeth having curved surfaces to preventsaid teeth from tearing said belt, and said plate having triangularshaped recesses, whereby to aid said plate t0 bend to conform to thecurved surface of a pulley.

2. In a belt fastener, a flexible plate having a quadrilateral shape, athickness tapering from its center portion toward either end thereof,and triangular shaped recesses in either end, whereby to aid said plateto bend, teeth disposed in rows adjacent the center portion of theplate, and adapt-ed lto engage the ends of a belt, and a tooth disposedat either end of the plate, whereby to steady the grip of the firstmentioned teeth on the ends of the belt and thereby prevent said beltfrom wabbling.

3. In a belt fastener, a flexible plate having a quadrilateral shape, athickness tapering from its center portion toward either end thereof,and triangular shaped recesses in either end, whereby to aid said plateto` bend to conform to the curved surface of a1 pulley, two rows ofteeth disposed adjacent copis of this patent may be obtained for fivecents each, by addressing the ""iinisionerof resiente,

Vthe.center andv widerV portion'of said plate,

a tooth disposed at either end of the'plate,

whereby tosteady thepiill of the aforemenadjacent the `edge thereofagainst ,which the pull` of the belt is exerted, to thereby prevent saidteeth from tearing said belt, sub-' stantially as described. Y

In testimony whereof Irhave affixed my signature in the presence of twoWitnesses.
